Referring' to the drawings and to the particular embodiment of ourinvention thereA shown. we have' therein illustrated in lgs. 75 l to 12inclusive a machine wherein the spool. carrying the tutt yarns woundvthere# on, may be placed and held in such relation to the tubes of atube traine that, by a single operation, the entire series ot' tutt- S0yarns inaybe placed or inserted with great certainty and accuracy7through the tubes by suitable yarn-placing means, herein a seriesoineedles, one for each tube.

Referring lirst to the preparation of the S5 tu'ltyarnsprior toinstallation in the tubingf niachine we have shown in lligs. i3 to 1,7inclusive ineans whereby the tutt yarns, ai'ter being wound upon 'thespool in the spooling machine7 inayv be held separated, 90 andmaintained in such separated condition while placed in the tubingrmachine so that tt y niay 'be drawn accurately through the `.ies of thetube inclusive we form ot' spooling machine -lv is represented in Figs.13 and l5, the. same being provided with well-known mechanism t'orreceiving the spool 5 and windingthe tul't yarns about the same. .Duringsuch operation the yarns unwind from bobbins (not shown), the `usualreed or separator (i being provided which presents upright pegs or theirequivalents T for separating and keeping separated the individual yarnstrands or groups ot' strands as the-y pass to the spool. The comb issupported with its teeth in upright position by a suitable holder Simmediately beneath the tut't' yarns as the latter p ass from the reedto the spool, so that, when the comb is elevated (Fig. 1(3) the teethare caused to pass between the sets of strands, as shown in Fig. 1.1.

llvhen constructed of sheet metal the lower edge of comb is preferablyturned or curled over on itself, as shown, and is adapted to rest in agroove or pocket in the holder S. This consists of a cross-bar extendingbetween the upright end supports 9, which latter are slidably mountedlin brackets l() secured to the frame of'the spooling machine. F orraising and lowering the reed the end supports are each provided withrack teeth 11 which mesh with the pinions 12, the latter being fixed tothe shaft' 13 extending transversely the machine beneath the reed (S,each end of the shaft being pro,- vided with -a handle 14 whereby it maybe turned and the comb raised 0r lowered at will.

The comb, when inserted in the holder, tits between two transverse pins15, so that the teeth of the comb are caused'v positively to` aline withthe pegs in the reed and to pass with certainty between adjacent yarn'strands lor s'ets of strands when the comb is raised.

After the spooling operation, the comb which has previously beeninserted in the depressed holder 8 and is then positioned as shown inFig. 15, is-elevated to the position shown in Fig. Gby turning thehandle l-l, each set of strands entering a separate space between theteeth of the comb. Suitable means for maintaining the holder elevatedarc-preferably provided, such for example, the pin 16 fixed to the lowerend of the supporting rod 9 and adapted to be yieldably clasped. and"held by the stationary spring clip 17 when the holder and comb areelevated.

lilith the holder elevated, the yarns are prevented from slipping out ofthe comb by the application thereto of a cap piece or retainer 1.8,which latter preferably consists of a bent or turned over metallic stripadapted to slip over. the points of teeth (as shown in Fig. 17) andclose the mouths of theslits against the eiiit of the yarn strands,preferably, however, without clamping or gripdescribed.

lThe attachingr springs2() arc preferably ping the. yarns or otherwisepreventing their free longitudinal dral't between the teeth.

The cap may be retained on the comb in any suitable manncr as. l'orexample. b v

means ol a resilient linger piece 1.) (one ol'4 which is shown in Figs.1l and il) riveted or otherwise secured` one at cach end of the comb,and having a hooked end which over-.

may be performed, the comb cannot be accidentally displaced. In thedescribed embodiment of our invention (Fig. l1) we have shown the combprovided at ,each end with an attachment member, hereiniir the form oilaspring 20. l`hejlal ver has an eye .l which (sce Fig. 5) mayj, slippedover the small pintle. 22 at the end of the spool 5 and employed'to?attach the. combv to theI spool, the former having first been laid'flatwise against the wound-on yarn. AThe wound-on yarn strands can thenbe severed, leaving them infthe'condition represented in Fig. andthe'spooling operation can thereafter proceed in the usual manner, andthe operation repeated as -toanother spool as above each provided withmeans, such as the angular clip 23 whereby the operative can readilyapply the spring eye 21 to the pintle or release the same therefrom. Itwill be seen that this provides a means for permanently holding the combin definite relation to the spool and the wound-on yarn .strands untilrequired tor the tubing operaprises end frame members 2i between which,

near the front of the machine, there extends a bed 'piece or plate 2 5(Fig. 3). The bed plate serves as a support or rest for the tube frame(see Fig. 9), which latter is inserted in the machine 'with the tubes 26resting on the bed plate and their small ends pointing inwardly, thetube connecting bar 27 resting against the 'front edge of the bed plate.

the indiridual tubes, sneh means herein be ing embodied in the torni ot'a swingingr clanip bar (Fig. if). which latter is piv .oted in uprightbrackets 3l mounted upon the end ot the bed plate and provided at oneend with the hand lever 32, sti that it can .he swuiig into or out ofengagementwith the tubesA The clamp ha along its active ,edge

is ,provided with teeth or serrations 33 (see Figs. S andst) which areadapted to enter and fit thespaees or depression between adjacent tubes,so that. when -the clamp bar Yissivung' over from the dotted lineposition shown in Fig. S) to the full line position there shown, the'teeth enter between the tubes and clamp' the tube. t' 'ame in alinementwith the'needles. The rear corners ot' theteeth, or those which tirstengagethe tubes, are preiferablvY beveled or otherwise shaped so thattheyv act as wedges and, enterin;r between the tubes, wedge the tubeLt'rame laterally into the required alinement with the needles if theformer happens to be slightly oti'set to one side or the other of therequired position. By this means the tube` traine is not only heldclamped, but is automat'icallyl broughtwith certainty into the requiredaline'ment.

Referring now to the means tor mstalling and holding the spool and thewound-on' yarn strands in the machine. the latter is provided withholders or boxes 2li depending* from the bed plate, in which holders theends or heads ot' the spool are placed. After the spool inserted itislocked at each holder against' turningr in the holder or withdrawaltherefrom by means of a locliing dogg or shoe 35 pivoted thereon.- Tocontrol the locking dogs simultaneous@r t'orthel locking or release ofthe spool, each dogV is provided with a pin 3G which projects up througha slot 37 (see Fig'. l!) in the transverse locking bar BS. The barextends across the machine terminating' in a portion 59, bent as shownin File. i or otherwise suitably toi-ined, to permit the operator ttograsp and move thel same. YThe holdin;Y brackets or hangers Bt are,transversely slotted to slidably'support the bar, the latter being heldin such slots by the angle clips llt).

The slots 37 in the locking har which receive the pins on the lockingFdogs are so inelinedV that, as` thevbar is slid transversely themachine. the locking;r dogs are .swungr up or downi the latter positionbeing represented in l"i;.9. When swung up` the dogs permit theintrraluction or withdrawal ot' the spool heads trom the holders. hutwhen swung down. assume the position shown in Figi. "J where they reachout along the edges thereot to a sullicient `extent to retain the spoolin the holder. s shown in Fig, Uthe contactinglr edges ot' the dogs areprovided with teeth il which are adapted to grip the wooden ledges otthe spool head. there being provided a springr t2. in each holder whichtends to throw the spool out against the dog. The teeth are so shapedthat the;y

oppose the nnwinding movement 'ot' 'the thus readiliY t'ree the spool'tounwind it. or

Having locked thc spool in the holder the operator disconnects the combfrom the spool. and after pressing back the spool in the holder jto`release it and unwind .a sutlicient length of yarn, he place-s the'coxnbin a Lrooved comb holdert3 located in front ot' and at a level justabove. the tube traine, the .varn strani'ls there'tor assuming theposition shown bv dotted lines in.

1.13 and o.. 'die needles it; ot: which there isV 'one toi-each tube.a`re 'carried upon a suitzahlrtrosshead or'holder 4 5 at the rear oftlieinachine an'd are'so arinnged that, at the propertime. they, may beprojected torwaidl v each thro/ruiltl one of thel tubes to seize a yarnstrand or strands and draw the same A/tl'irougi ,its tube from thelarger to the smaller eudtl'iercot'. The needle cross-head t3. asshownin Figs. l and 3, is tixedlv secured at each end to a slide bar 46, thelatter adapted to slide through bearings or `iiiilc\\';r\'s. one otlwhich, t?, is supported at. the rear ot the 'frame piece 'l2-t and theother ot' which` 4S, is suspended Jfrom the bed plate 25..

To advance or retract the needles, the lower 4edge of each slide baretti is provided with rack teeth t!) which mesh with gears 50,

the latter secured to the main operating: shatt The. shaft 5l is turned(see Figs.l l, 2. l and 4) by means of pinions 52 secured one at eachend thereof` and meshing with a gear segment 53,.the latter carried backby a lever arm 54 pivoted at to the lst) frame. The two levers 54 atopposite sides vof the machine are connected by the transvhooks to beseized by the latter on their return. ln the presentembodiment of ourinvention this is accomplished by shifting the transfer comb itself.this acting, because of the close relation which thetransfer comb bearsto the. needles and tubes to lay the varn strands with certainty. acrossthe yneedles and within the hooked portions thereof, as represented inFig. 7. Preferably the shifting operation is performed imwhanieally andimniediately following and consequent upon the assumption by the needlesof their extreme advanced position. asshown in Fig. (3. '.lo this endthe holder alii of the transfer comb is provided at opposite ends withslotted extension portions 57 and 5S, which are slidably supportedbetween ears formed by projections of the supporting brackets 31. Thebracket ears are provided with fixed pinsl 59 which engage the slots inthe holder and permit a limited sliding movement of the latter with itsattached comb. The projecting end of the holder portion '57 (Figs. l, 2and 7) is provided with an upright lug (3U-which is secured thereto bymeans of a stud (3l passing through a slot (S2 in the holder so as topermit slight longitudinal adjustment of the lingr thereon. The lug isprovided with a rearwardly projecting pin G3 which is engaged by theforked end of the upright arm (3lof a bell-crank lever which is pivotedupon the stud (55 secured to the bed plate 25.

The other arm 66 of the bell-crank carries a 'small roll G7 which isnormally pressed inward against the slide bar through the' medium of aspring 68 encircling the stud' 65 and having one end secured te thelever arm 6l and the other to the stud. W hen thus positioned, with theroll bearing against the slide bar the comb is held as represented inFig. 2 maintaining the yarn strands in vertical lines. Immediately backof the roll the slide bar is provided' with a cam member 69 havingpreferably a conical or wedge-shaped nose succeeded by a.circumferentially grooved portion so shaped as to form a seat for theroll. The cam member is loosely mounted on the slide bar so that, onadvancement of the needles, it remains fixed wherein their relatively tothe roll until the needles approach their eXtreme forward position. Thecam member the'n becomes engaged. by a pin 70, or other suitableabutn1ent,.f.ixed onthe slide member and this causes the advancement ofthe latterfrom the position shown in Fig. 3 to the position shown inFig. 6. The ad 'ance of the cam lifts the roll upon its conical nose andleaves it seated in the groove (it). Such movement swings the bellcrankabout its pivot shifting the holder and the comb from the' positionshown in Fig. 3 to that shown in Fig. 7.

The needles having been projected through the tubes and beyond the yarnstrands by movement of the operating bar 5G to the extreme upperposition, the operator then swings the bar down, causing the needleseach to retract and seize the yarn or yarns laid across its shank anddraw them through the appropriate tube. The return shifting movement ofthe comb, however, is preferably delayed until the needle hooks haveldrawn the yarns into the tubes, such return movement herein'not takingplace until the close of the, needle return movement. Here- .in thereturn of the comb and its holder to its initial position is effected bymeans of the abutment 71, shown in the form of a' 'asher secured to theforward end of the slide bar 46, which abutment engages the cam (39 anddraws it back'to its initial position, thereby releasing the roll andthe bellcrank, the pressure of the roll against the cam having actedmeanwhile to hold the cam fixed notwithstanding the movement of theslide rod. v

In the practical employment of these machines it is preferable that theneedles not only be guided close to the tubes prior to entering thesame, but that their hooked ends be rigidly spaced when out of use andretracted. Furthermore it isalso desirable to provide guidance for theends of the needles projecting through the tubes and before seizure ofthe yarn, otherwise the tubes which through misuse are apt to becomebent and out' of alinement, are likely to throw some'of the needles toone side or the other lof the desired position. y

'Herein we have provided guidance for the needles close to the mouths ofthe tubes Where they enter, the guiding means being capable ofretraction with the needles to permit the introduction of suitable yarnshearing or trimming devices between the tubes and the needles, and suchguiding means `hcrein also holds in rigid separation the l. Such guidebar is secured at its ends to supporting rods 73, ythe latter slidablyizo bar

" more@ 'thereby drawn 'forwardto brine the guide bar close to theneedle points when tbe latter ere retracted. The forv'vard movementofthe bar is limited by means of a pin 'in each rod, ivhiehpin abutsaga-inst the cross; bar or holder.

1When the needles are advanced the guide '72 is advanced with them untilthe needle hooks are close to the months of the tubes 'when the guidebar is brngbt to rest,

by abutting against a fixed part of the machine, herein the verticallyfixed Knife or the shearing mechanism to be later described (see Fig.6). The needles continue their ad- Vance through the tubes', v merelystretching the oonneeting'springs 74, the guide bar being subsequentlyreturned with the needles to the position shown in Fig. 3 after thelatter emerge from the tubes with the engaged yarn strands.-'

The needles are secured to the cross-bar between suitable spacingmembers by means of a key rod 77 of circular cross-section seated hal)cin each needle and half in e' plate 78 bolted to the top or" thecross-bar. To provide guidance for the needles on the opposite side ofthe tubes, means are provided whereby the needles, as they emerge fromthe tubes and before engaging the tuft yarns. are directed into ytheproper course )my suitable means may be employedfor.

this purpose and, it' desired, such guiding means may be carried andpresented by the swinging; rlainp bai-.30, but .herein tliere isprovided an additional member eornprisinga needle guide bar l extendingaei'oss niarhine and adapted to'be swung down di-l rectly back oillularge ends' off.' tbe ftnbes' 'and in the path of tbe needles as theyemerge therefrom.y Such needle guide (Figs. 2, 8' and El) isrurrieil ateach end upon arms pivoted in the brackets 3h near' the end of the bedplate and is provided at one end with a depending,Y lever arm 32 bymeans of whirh the guide bar can be swung fromthe Afull (line positionshown in. 9 to the dotted line or active position.

rlhe edge of 'the needle guide is' provided with teeth 83 (Fig. 8) whichare edaptedt swine; down in between the needles and, esv

' the latter emerge from tbe tubes, Wedge such as are' out ot' alinementinto the required :ilinemenh Herein the needle rinde 1s depressed bymeehanlcal means and properly timed with relation Vto the needleadyance.

For this purpose the arm 82, normally drawn back by the spring' 84,Whichi has its' opposite end secured to the bed plate to hold the needleguide up, isl thrown for-Werd to swing' 'the needle guide down, asdescribed, by means of a pin S5, or other suitable. part;

ixerlly secured to the slide-rod 46. This pin engages the lever 82 andswings the needle guide down. This `preferably takes 'fplaee justfastheneedles emerge `from the tnbeegaand the lever is provided with aninclined end which .rides upon the pin as the needles continue'oadvance, so that 'the needle guide, when swung downJ is held there untilthe needles have seized the yarn strands anddrawn them back into thetubes, whereupon, the pin 85 moves back and allows the lever 82 to drop.The lever arm is shown as engaged by the pin 85,111 the' vdotted lineposition shown in Fig. 9.

Prior to use in the loom it is neoessary to out the drawn-in yarnstrands evenly at a Lined predetermined distance .from the ends l,

of the tubes. Herein .we have provided shearing means whereby this isautomatically accomplished in 'the same operation'v with tbe tubingf ofthe yarns. To this end there is provided vdie vertically iixeeljrniie76, already referred to which, however., is supported at the rear edgeof 'the bed plate so as to be capable of e. slight yielding movementtoward the plate. secure this, the knife is supported on stnds'fi (Fig.10) each slidably mounted in a pocket in the bed plate and provided withan upright pin 87' working in' o small transverse slot 88 in the plate.Relatively 'still' springs 89 areseated at intervals in the bed plateand bear against the knife to force the latter bark and the. pins 87 tothe rearward limit of the slots 88. The threadsr of the yarn strandswhen drawn boel; by the needles, lie directly over .the upper edge oftheknife 76 and in that position are cut ed" bya' downward movement of tbevertically movable knife 9G. The-latter has an inelined'edge, as shownin l dotted outline in Fig. 2 andat its extreme le 't hand end, aeyiewedinl Fig. 2, which. end, when depressedy irs'trneets the fixed finireblade, it is connected to a cem mein ber 30X leaving a lower bevelededge as shown at 9i in Fig. 6. The blades are so arranged tbet tbevertically movable blade'SO, when eieveted, lies somewhat over thestationary 'fixed blade, and when depressed,v acts first through einecom member 9G* and subsequently through the blade member 90 itself towedge the blade 76 forward against the ILOG @fielding springs 8 9. Thus,as each sueceed l fing portion or' the bladeedges cross, the shearing;Iaction is accomplished by a press ing beek of tbe'stationary fixedblade, 4thus givingin efi'ect the action ot' a pair of shears andimparting a clean shearing cutjto thel yarn. Y i, To impart suitable andapproiriately timed movement to the vertical Inovableblade, the latteris bolted to the transverse' supporting beam 92 which, in turn; islixedly secured at each end to) vertiea lly reciprocable plunger rods93, the latte? ftfuided for sliding movement in opper and lower brackets94 and 95 attached at the traine, member 24. Une side of eaeh plungerrod 93 is toothed vto form a rat-k 9U, and this engages in earh -easewith a pinion 9T, the latter seeured to the shaft 5l whieh earries themain driving gear 5; and the needle operating gear 39. 'i`he parts areso geared that, as the needles are retraeted out of the path of theshearing nieelianisni. the latter deseends from the position shown inFig. ti to that shown in Figs. 3 and 9, and trims the ends of the drawnyarns. hand, when the needles are advanced. the

upper blade member is lifted up and out ot" their path.

In praetiee it is quitenecessary that the projeeting ends of thedrawn-in varns should be triimiied evenly and with eertainty to therequired distanee from the ends of the tubes. ln order that the tubeframe. when withdrawn from the maehine. may have the varn strands eutthe required length and -may also be held fixed in this relation on thespool. thus being ready for theloom with-- outy the need of any furtherstep or operation. means are preferably provided so that, aftershearing. and preferably when slieai'ed the endsof the yarn strands areheld elaniped andthe tubeframe is also held elamped.

'lhis permits the operator to remove the spool from its holder. wind upthe slaeli varn thereon and apply the spool to the tube frame byinserting pintles 2L thereof in the end springs 9S. 'lhe latter areeustoiuarilv provided on the tube frame and. wheu-the latter isinstalled in the. maehine. project outwardly from the maehine as shownin -Figs Zi and (i. 'lhe spool then oeeupies the position shown indotted lilies in Fig. 9 and the tube fi'ame. spool and yarn ends being'.

definitely and tixedly positioned each relatively to the other'` thetube franie, and yarn ends may be released and withdrawn from themaehiue for use in the loom without turther attention. To this end wehave provided elaniping or holding means for elaniping they yarn strandsbetween the small ends of the tubes and the knife. Such clamping meansmay be embodied in various forms, but herein we have piovided a holdingbar 99 exteiu'ling across the machine and 0&1'

'riedby the shearing mechanism so that,

when the needles are advaneed, such bar is elevated with the knife 90.out of the way, as shown in Fig. (3. hen the needles are retraeted,however, and the shearing blade descends, the holding bai' is broughtdown across the drawn-in yarn ends clamping them' tight against tli'eflat topof the bed plate 25', as shown in Fig. 9.

Preferably,y though not necessarily, 'the holding bar engages with theyarns just prior to the shearing operatiom so that, before being cut,the yarns are g'ipped tight over the bed plateand relatively near the()n the other .baia and 'aeting to depress the holding bar to itslowermost position -(Fig. (i). Its downward movement is. limited by anabutment. sueh as the eollar I1025 carried by eachv pin. whieh abutmenteontaets with the upper side of the beam supporting arin 191. (in thedepression of the shearing blade the holder bar elamps the drawn-inyarns ]ust prior to the shearing eut.y subsequent depression of theblade resulting merely in rompressmg more or less the springs 192. l`heholder bar may be of any suitable material and of any desired shape butherein isA formed of la metal strip or' plate with a lower rounded orbeveled edge;

ln order-that the varns may be, released from the holder bar for thewitlidra 'al of the spool and tube frame fioin the machine, asdeseribed. while still leaving the needles retraeted and the shearingblade depressed (in whieh position it will benoted the parts i are rwdyfor the drawing-in of the neXt set vided'with a forwardly directedfinger 104 whiehjtsee Fig. 9) overlies` the clamp bar.` it() so that,when the latter is swung up by its handle 3;. the bar engages the. twofingers lll-i and lifts the holder bai-- 99 against the eompressionsprings 102 so that the yarn ends are free to be withdrawn from the mivehine with the spool and tube franie. The elevated position of theholder bar and fingers will be elear from the dotted line shown in Fig.9. The operator, therefore, having drawn in and trimmed the yarnstrands, releases the spool by movement. of the releasing bar 43. windsup the slaclton the spool and fastens the latter to the tube framesprings 98, as described, the yarns mean- Movement ofthe handle 32thereupon serves restoringI For this purpose each to release both thetube frame and the yarns ing"r machine with the connected yarn strands.'

K means of the upright positioning pin lol;

shown at the lett-hand end of the bed plate7 as viewed in Fig. 2.corresponding pin might be employed for the opposite end of the tulrame, butpreferably one end only is'po's oned so that the operator willplace the tube frame in' the machine with refer ence to the pin 106,allowing the alinement clamp 30, when subsequently applied, to en-rforce, if needed, a delinite alineinent with the needles.

It will thus be seen that the yarn transfer comb is definitely andpredeterminately related first to the reed pins in the windingY machineand later to"th'e.ncedles and tubes in the tubing machine so that theyarns are received from the bobbins, then transferred and laterpresented to the needles for the tubing operation by the sameinstrumentality, c. the transfer comb. Large num-- bers of transfercombs may be employed in practice of standard dimensions so that, not"only may the same comb be repeatedly ap plied to the winding machine,with assurance that the teeth will exactly aline with .the reed pinsT orto the tubing machine with assurance that the teeth willexactly alinewith the needles and tubes, but successive standard combsA may he usedin each machine 'with certainty that the yarns held hy one clamp willhear exactly the same relation to the reed pins, needles and tubes astheyarns held by another clamp where the same pattern has been used'in eachcase. rlhis not only provides effectually fot-'the transference of theyarn strands from 'one machine to the other and for the tubing of theyarns l *with the minimum chances of disarrangev :the operator.

ment inthe intendedpattern, lout by the use of a single standardinstrument of transferpinsL great rapidity of operation is secured witha minimum of attention on. the part of .The provision also for theefl'ectual guidance of the needle both in en.- tering and'emerging fromopposite ends of the tubes practically enforces and' insures the drawingin every instance of the intended pattern.
